I recently upgraded to 13.10. The installation seemed to run fine, after the system rebooted I got the error "The system is running in low-graphics mode” After a few hours of googling no solution I found fixed this problem.
I tried to downgrade using a disk and got the same error after installation. I then tried to back up my files using the disk by selecting "try ubuntu".
I really need to recover my data, I have weeks worth of work on there and some bitcoin I cannot afford to lose.
Any help would be greatly appreciated.
